DEFINITION
Classification: 226/124
(under subclass 120) Device provided with a continuously driven roll* mounted on a carriage, which carriage moves to and fro, (either rectilinearly or arcuately).
(1) Note. In the operation of the devices classified herein, the average speed of the carriage in retrograde direction (i.e., opposite to feed direction) approximates the peripheral speed of the roll in feed direction such that retrograde movement of the carriage nullifies the feed movement imparted by the roll, to effect interruption of material-advance.
